The Curious Science of Warfare

Full episode of NPR’s ‘Fresh Air’ featuring author Mary Roach

In her book Grunt, on the stranger side of science that helps keep our soldiers alive on the battlefield, author Mary Roach delves into a world that would make most of us squeamish. Here’s her discussing maggots in World War I:
